I downloaded your software to try to fix a very annoying bug my website has. Your SW is awesome, really!

BTW, the bug stays somewhere in my cookies...there is a call to setcookie() which is not working and the cookies are not being set.
To fix the bug i need to see the result of the function setcookie() to see if it actually works or not.

How can i see immediately if setcookie() is working or not?
How can i see cookies like variables (changing after each debug step)?

The variable $_COOKIE is not an option, because it's not updated immediately after setcookie, but on the following request.
